In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers. The process of setting a jumper is often called strapping.

What is the purpose of the jumper?
When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit. Jumpers can be added or removed to change the function or performance of a PC component. A group of jumpers is sometimes called a jumper block .
What is the use of jumper in HDD?
A jumper may also be referred to as a jumper shunt or shunt. Jumpers manually configure computer peripherals, such as the motherboard, hard drives, modems, sound cards, and other components. For example, if your motherboard supported intrusion detection, a jumper can be set to enable or disable this feature.
What is a jumper on a board?
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The wire connects the pins and creates a circuit. To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
What is jumper in mobile repairing?
Jumper wire is used to solder and connect one point of the PCB track with another point. This is generally done when some SMD Electronic Components or IC is faulty and is not easily available in the market. Jumper wire is available in different diameters. It is basically a thin copper wire with laminate.
Where is jumper in motherboard?
Open up the system so you can see the motherboard. Locate the CMOS jumper by referring to the motherboard manual and how to clear the CMOS. In general, the CMOS jumper is three pins located near the battery. In general, CMOS jumper has positions 1–2 and 2–3.
Do SATA HDD need jumpers?
If you are using SATA drives, you do not need to set jumpers for master and slave because each drive gets its own cable.
Do SSD drives have jumpers?
Distinguished. Some SATA drives have a jumper but it’s only used to force a newer drive to run slower. SATA speeds have changed from 1.5 to 3.0 and now to 6 Gigabits per second.
Do SATA drives have jumpers?
On SATA-II drives, a jumper is sometimes used to set the drive into SATA-I mode for compatibility with older controllers. Show activity on this post. Some SATA drives have jumpers to enable/disable 3Gb/s functionality or other backwards compatibility items.
Is jumper a switch?
Supplied in units of 1 thru 16 poles they provide an alternative to jumpers without the need for ‘parking pins’ on the PCB or exposed bare pins and are available with ON/OFF (JSA4), CHANGEOVER (JSC4), and CENTRE-OFF (JSK9) switch actions.

Why jumpers are used in transmission lines?
A jumper is a conductor that is rated to carry full line (load plus capacitive charging) current and is installed to connect line spans on opposite sides of a deadend or a large angle structure. The jumper is installed on each phase of the line and operates at full line voltage.
What is a USB jumper?
By my definition, a jumper is a small two pronged tool used to connect two electrical inputs and ‘jump’ power between them.
What is GND in mobile phone?
Ground, in the context of electronics, is the reference point for all signals or a common path in an electrical circuit where all of the voltages can be measured from. This is also called the common drain since the voltage measurement along it is zero.
What are the tools and materials needed in Jumpering techniques?
It is important to first track and find the fault or missing track and then do the jumper.
Tools Needed to Jumper
- Jumper wire.
- Precision Screwdriver.
- Soldering iron or Soldering Station.
- Solder wire.
- Blade cutter.
- Multimeter.
- Soldering flux.
- PCB holder.
Can you clear CMOS without jumper?
If there is no CLR_CMOS jumpers or [CMOS_SW] button on the motherboard, please follow the steps to clear CMOS: Take out the battery gently and put it aside for about 10 minutes or longer. (Or you can use a metal object to connect the two pins in the battery holder to make them short-circuited.)
Is it safe to reset BIOS?
Resetting the bios shouldn’t have any effect or damage your computer in any way. All it does is reset everything to it’s default. As for your old CPU being frequency locked to what your old one was, it could be settings, or it could also be a CPU which is not (fully) supported by your current bios.
Why PC turn on but no display?
Without RAM, your computer can’t function, which means your display will be black when you turn it on. If you think this is the cause of your display problem, try reseating the RAM or installing new ones.
Do I need a jumper on my hard drive?
For IDE hard drives, it’s important to properly set the jumpers. If not properly done, your computer may not boot or the hard drive won’t be detected.
What is the jumper on SSD?
You may have pins on the back of your hard drive that nothing is connected to. These pins are called jumpers, and are used to enable specific types of settings.
What are the 3 connections on a HDD?
There are three main types of hard drive data cables: IDE/PATA, SATA and SCSI.
Why wont my HDD pop up?
If your internal hard drive is not showing up, it might be because it is not initialized or it needs formatting. Make sure your disk is properly connected to the motherboard with the SATA cable. Your HDD might also not be visible in Windows 10 due to some BIOS settings.
